Mathcad

Heyho,best thx to the forum i could manage a nealry complete automatisation of many calculations.Now i have more difficult Problems and i hope i can solve it.I have now very complicated equations and the way to calculate a certain value is per iterativ methode.Now for example i need to calculate a Force:F=f(.....variables....b)Now at beginn i calculate b with a startening equation (gives a startening point of b)The next step is to calculate the force.After the Force (initial force which gives a value but is not the right force) was calculatedThe problem is now: For a detailed calculation, the variable b is depending on the force, which was calculated before.so:F=f(.....variables....b)b=f(....variables....F) --> there are 2 equations for b .... an initial equation which is simple and the complicated one (b=f(....variables....F))So for me looks this like an iterative solving. I was thinking: I want to start with the initial b and F value and change F, so that the residum of b is less

Hello,I was wondering why when I define a counter variable like "i" and assign it to a vector the result display a "..." and not the actual value I just assigned to the vector.It is a little annoying to have to type out the variable again to display the value, I would like it to display correctly without having to retype the variable.See below:

Good Morning Community,I have having a hiccup here with a file I have put a substantial bit of work into.  The file has been working fine for weeks including this morning however now I am getting an error listed:The file type is not supported.Log is located atC:\ProgramData\PTC\Matchcad Prime\Logs\MathcadPrime_Exception_20151208_095225.logCan anyone please assist me in recovering this file?  I have a backup saved from yesterday but I'd hate to reverse almost a full man day of work!Thanks so much,--Adam

0down votefavorite I want to simplifying radicals in Mathcad. I have expression with product of radicals and want use this rule of transformation:The product of the square roots of each factor is equal to the square root of a productHow I can do it? For example,  srqt(a)*srqt(b) as sqrt(ab); sqrt(a-1)*sqrt(a+1) as sqrt(a^2-1). Comment I have complex expression that can simplify by use last transformation, but Mathcad don't view how simplify it, how explain Mathcad use above rule?

how can i find arc tangent?

In the x-y plot,the plots are not copying to thepowerpoint clearly, when I choose dotted lines(Traces--> line-->dotted lines)Please go through the attached filefor clear understanding of my question.Please help.

I have created a programme for Mone Carlo Simulations but now want to get an output table to show what would happen if I created more and more simulations.In the attached file the basic problem is using 1000 simulations which returns 0 failures in my problem. However, I want to see what happens as the number of simulations (Nsim) increases i.e. I want a table with Nsim in one column increasing and the number of failures in another column also increasing.Any help really appreciated.

Hi everyone,I met a question, when I use "pdesolve" in mathcad. The failure is listed in the picture as following:It told me that the second-order are not allowed, but I have another successful example from the website, which can be seen in the following picture:In the above successful case, we can see it also contains uxx(x,t), which is second-order derivative. Anyone can help me about my failure in my case? I attach my input file in the annex, please kindly find it.Best wishes,Jason

Hello all, i am new here and struggling to get this transfered.My current setup was MathCAD 14 on uses workstation with a Floating license install on a Windows XP .I decided to move this to an official license server running Windows Server 2008R2 64bits. I contacted PTC License management to generate me a new floating license with my new info which they did.I tried to install the PTC License Server with WildFire 5.0 ( M050) but i am never poped the question to browse to my license file. When the installation completes it only seems to have copied the install files here : C:\Program Files\ptc_customThe deamon - lmgrd.exe are no where to be found. I presently have LMTools running other licenses on this server so i decided to configure a new one for MathCAD. I open LMTools go under Config Services and createa new one. I copied the old deamon from the other machine ( ptcd_exe ) and used another lmgrd file from another application. All gets created ok but the Windows service one created doe

Hello,I have a prob. i don't have the source media to install on W2012 64 B to instal PTC licence Tools on the server 2012 .I have the new licence txt but not the program. I tried to copy mnually ( it is not the best i know ) the folder on C:\Program Files\flexnet\ from XP sever to Windows 2012 and good configured the service lmtools with the the new key PTc sent me. but ir says when i start the server : Server Start Failed. The Server May Already Be Running!! Reread Server Failed, and the service don't flexlm service 1 don't want to start..lmgrd is not running: License server machine is down or not responding. See the system adminstrator about starting the license server system, or make sure you're referring to the right host (see LM_LICENSE_FILE).Hostname:      __HOSTNAME__License path:  7788@__HOSTNAME__FLEXnet Licensing error:-96,7.  System Error: 11001 "WinSock: Host not found (HOST_NOT_FOUND)"I think i gave need a new version compatible in W212

Hi,I'm a newby with Mathcad Prime and I'd like to know how can I use trigonometrics symbolism, ie 90 degrees angle like pi/2 or cos of 0.36 radians like 3 times square root of 73 fraction 73 and so on.Mathcad returns me the approximate decimal numbers and not the symbolic fraction or the symbolic pi.Thanks in advance

Hello all,is it possible to use symbolics calculation within a programming box in MathCad Prime 3.1? In particular I'd need to solve an equation using symbolics evaluation (float,32) and use the obtained result,that is a real number, for further calculation within the same programming box.Thank you!Domenico

To all,I am trying to see if one can find a parameter required to fit a known equation to a set of data points. See attached. I have an equation Q(w,wn,zeta) and would like to see if it 's possible to find the value of zeta required to fit the Q() for a given data set  Test 1: For a given range of w values, a value of wm and zeta = 0.04, I calculated the Q value, allocated them to a table to “mimic” a data set (not important but it follows how data is provided. I am trying to work “backward” by trying to find the zeta value required to fits Q at the max value. (Obviously mcad must predict zeta  =0.04 !) I have set up ‘test 1’ as a root() but nothing is return  Test 2:  Use a subset of a known data set and see if one can find the zeta value required to fit Q() passing through 3 points of that subset I know that must people will say that I am tackling the problem the wrong way but I have to start somewhere and that why I am looking for advice Any pointers by the mor

Dear All,I need to change computer and as MC11 is no longer supported I was trying to define where I could find the activation key on my old computer. Any ideas?Thank you in advance

I have an equation that is long and extends past the edge of the formatted page.  How can I get the equation to wrap to the next line?

In larger documents with several figures inserted using clipboard I have seen the following behaviour.While working on the document it seems ok. Figures are places where I placed them etc.After having closed the document and Mathcad and then re-opening the document I find that several (but not all) of the figures are shuffled around. Have you seen similar? This is an extremely critical bug to us.Kind regards,Michael

Title pretty much sums it up.I've been using Mathcad 15 for almost a year with a license which runs through my school's server. So it's a server license.One day it just wouldn't launch. I've tried everything from re-installing to running it in compatibility mode.Please help if you can!(maybe) relevant info:Windows 10Lenovo laptopThanks in advance, Kevin.

I have create a set of random locations and then at each location I place an object to simualte an image.The delta just makes sure no objects are within 3 pixels of the image edge.I know want to be able to change the locations now to represent the following regular pattern. I believe horizontallt there is a pitch of 8 pixels, and vertically a pitch of 9 pixels with a horiztonal shift of 4 pixels.Thnaks for any helpJason

how can I write "otherwise" in mathCAD prime 3

Hello,i am using mathcad 15. i am not sure why M1(x) and M2(x) yield different results. the term shaded blue is the same in both functions. The second term shaded green, in M2(x) , i just simplified more than the one in M1(x) . So i was expecting to see the same results for M1 and M2. But i am not sure what i am doing wrong. Thank you!

How can I do this in mathcad prime 3

To allI have searched in the doc (signal processing) but cannot any function doing the "half power" (frequency) band.if I have a set of data (X,Y) and a known point (Xn,Yn), I want to know the 2 co-ordinates X1 & X2 [(X1,Y1) & (X2,Y2)]  so thatY1=Y2 = Yn/sqrt(2). Set up a simple "search" function but surely there must be something in mathcad!ThanksReqgads

hi, this can't be hard can it?.. am new to mathcad and am trying to import 3 columns x12 rows of excel data by copy/paste into a table and/or a matrix etc with the intention of plotting on a 3d surface graph...I can paste the values into the mathcad matrix ok but can't seem to assign a variable name to the matrix... so graph can't load it (nor can anything else refer to it I suppose)...the table rows/columns aren't read in from the excel data - they are presumed 0, 1, 2 etc - so axes are preset to 0, 1, 2... rather than 1st 2 columns of data in excel file - graph just plots 3 columns of data imported as if they were functions f({0, 1, 2}, {0, 1, 2})... which seems a bit dim ...(my 3 columns in excel are the x, y, z) function should be {excel col3} = f({excel col1}, {excel col2})I must be missing something obvious - can anyone help?lots of thanks
